When I try to update any container I get the following error message:
Get "https://registry-1.docker.io/v2/": dial tcp: lookup registry-1.docker.io on [::1]:53: read udp [::1]:55074->[::1]:53: read: connection refused
This might have happened after setting up pi-hole container using this guide:
Pi-Hole in Docker on Synology- The Best Way! - ServiceMax
Is there any configuration that I'm missing?
Thank you
